Abstract

The embodiment of the invention provides a linear image correction method and system for laser imaging and related equipment, which are used for solving the problem of geometric distortion of a linear image in a laser imaging process. In the embodiment of the invention, the image correction system takes a direction opposite to the offset of a target line segment as a correction direction, takes the offset of the target line segment in the X-axis direction as a correction distance, moves the pixel row where the target line segment is located so as to generate the correction image, so that laser imaging equipment can offset the offset of the image in the X-axis direction in the exposure imaging process . Meanwhile, in the corrected image, the correction distances of the pixel points on the same target line segment are the same, the corrected target line segment is still perpendicular to the X-axis direction, and the edge of the vertical line segment has no convex pixel points similar to the oblique line edge, so that sawteeth similar to that of the oblique line image edge in the laser exposure process can be effectively avoided, and the straightness of the linear image after exposure imaging is ensured.

Description

technical field [0001] The invention relates to the technical field of laser imaging, in particular to a linear image correction method, system and related equipment for laser imaging. Background technique [0002] The principle of laser imaging is: control the laser to irradiate the photosensitive coating on the exposure surface for image exposure, and generate a preset image after development. Compared with traditional technology, laser imaging technology reduces process complexity and saves production costs, and is widely used in screen printing plate making, PCB manufacturing and other fields. [0003] The applicant noticed that due to factors such as installation error of the laser, inconsistency of the spot offset of the laser on the exposure surface, and deviation of scanning displacement, etc., during the laser exposure process, the linear image after development on the photosensitive adhesive coating tends to be relatively Geometric distortion occurs in the templat...
